For example, `sameSex' is not reflexive on the set of all humans.  It is 
reflexive on the set of women or the set of men.
And the relation `sameSpecies' would be reflexive on the set of all 
humans.  The relation `sameSex' has more discrimination power than 
`sameSpecies'..

(It's not clear to me why I would want to organize the world into 
reflexive sets in the first place, other than to simplify things that 
are the same on certain dimensions.)
